Suppose that minor errors occur on a computer in a space station, which will require re-calculation. Assume the occurrence of er

Molodets [167]

Answer:

$P(X = 0) = 0.6065$

$P(x < 25 ) = 1.18 *10^{-33}$

$P(x \le 5 ) = 0.9994$

Step-by-step explanation:

From the question we are told that

The rate is $\lambda = \frac{1}{2}\ hr^{-1}$ = 0.5 / hr

Generally Poisson distribution formula is mathematically represented as

$P(X = x) = \frac{(\lambda t) ^x e^{-\lambda t }}{x!}$

Generally the probability that no error occurred during a day is mathematically represented as

Here t = 1 hour according to question a

$P(X = x) = \frac{\lambda^x e^{-\lambda}}{x!}$

Hence

$[tex]P(X = 0) = \frac{\frac{1}{2} ^0 e^{-\frac{1}{2}}}{0!}$

=> $P(X = 0) = 0.6065$

Generally the probability that a critical error occurs since the start of a day is mathematically represented as

Here t = 1 hour according to question a

$P(X = x) = \frac{\lambda^x e^{-\lambda}}{x!}$

Hence

$P(x \ge 25 ) = 1 - P(x < 25 )$

Here

$P(x < 25 ) = \sum_{x=0}^{24} \frac{e^{-\lambda} * \lambda^{x}}{x!}$

=> $P(x < 25 ) = \frac{e^{-0.5} *0.5^{0}}{0!} + \cdots + \frac{e^{-0.5} *0.5^{24}}{24!}$

$P(x < 25 ) = 0.6065 + \cdots + \frac{e^{-0.5} *0.5^{24}}{6.204484 * 10^{23}}$

$P(x < 25 ) = 0.6065 + \cdots + 6.0*10^{-32}$

$P(x < 25 ) = 1.18 *10^{-33}$

Considering question c

Here t = 2

Gnerally given that the system just started up and an error occurred the probability the next reset will occur within 2 hours

$P(x \le 5 ) = \sum_{n=0}^{5} \frac{(\lambda t) ^x e^{-\lambda t }}{x!}$

=> $P(x \le 5 ) = \frac{(0.5 * 2) ^ 0 e^{- 0.5 * 2 }}{0!} + \cdots + \frac{(0.5 * 2) ^ 5 e^{- 0.5 * 2 }}{5!}$

=> $P(x \le 5 ) = \frac{1* 2.7183 }{1 } + \cdots + \frac{1 *2.7183 }{120}$

=> $P(x \le 5 ) = 2.7183 + \cdots + 0.0226525$

$P(x \le 5 ) = 0.9994$
